For half a year Webmin has told me that “All installed packages are up to date”.
But for 2 years before that I had many new updates every week.
I wonder if something is wrong. How can the almost constant stream of updates just stop overnight?
My VPS OS is Ubuntu Linux 20.04.6
I use Webmin in a browser in Windows 11.
Presumably you disabled whatever repos were providing updates.
Since this is in the Webmin category, I guess you got it from the Webmin repo, so make sure you haven’t disabled that repo in /etc/apt/sources.list.d. There’s probably a file called webmin.list or something like that. (On a Virtualmin system, it’d be virtualmin.list or something along those lines.)
